By ending the life of Jean Senac on August 30, 1973 in Algiers, his assassins believed they would silence him forever. They were wrong since his voice is a little louder every day. Witnesses to these craze: the publication of the complete works of this great poet, the countless conferences and radio broadcasts devoted to him and finally the production of films such as "Jean Sénac, the blacksmith of the sun". The moving and overwhelming testimonies of those who knew him, the unpublished film archives, the generous voice of the poet on the radio, the discovery of his travels in the territories of poetry and politics make this film a precious document on the life of Jean Senac.
